{"schema":"threatline.record/2","record":{"id":"CVE-2026-100720","aliases":["GHSA-89vj-gqqr-73p8"],"summary":"Froxlor before 2.3.12 Stored XSS via SSL certificate issuer","details":"Froxlor 2.0.0 through 2.3.10 is vulnerable to stored cross-site scripting. When a customer (the lowest-privileged authenticated role) uploads an SSL certificate for one of their own domains, the Certificates API add()/update() methods parse it with openssl_x509_parse() and store the issuer organization (issuer['O']) value verbatim without sanitization. Froxlor's table-listing renderer then emits scalar cells through Twig's `raw` filter, disabling HTML auto-escaping, so when an administrator or reseller opens Domains > SSL certificates the attacker-supplied issuer value executes as script in the privileged user's session. This crosses a privilege boundary from customer to admin and can result in full administrator account takeover; because a Froxlor admin controls webserver, DNS, and PHP configuration applied by a cron job running as root, the issue can be further escalated to command execution as root on the managed server. The issue is fixed in Froxlor 2.3.12.","categories":["Unclassified"],"product":"froxlor","vendor":"froxlor","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100720","source_modified_at":"2026-09-26T23:02:23.814Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"froxlor","vendor":"froxlor","versions":[{"version":"2.0.0","status":"affected","versionType":"semver","lessThan":"2.3.12"},{"version":"2.3.12","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100720","source_modified_at":"2026-09-26T23:02:23.814Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"froxlor","ecosystem":null},"version":"2.3.12","basis":"first unaffected version stated in the CVE record"}],"cvss":9.3,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00215,"percentile":0.11337,"score_date":"2026-10-23"},"published_at":"2026-09-26T13:24:10.569Z","modified_at":"2026-09-26T23:02:23.814Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100720","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-26T23:02:23.814Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100720","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/froxlor/froxlor/security/advisories/GHSA-89vj-gqqr-73p8","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/froxlor-before-2.3.12-stored-xss-via-ssl-certificate-issuer","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-09-26T23:02:16.405840Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-26T23:02:23.814Z","content_hash":"b71715a787ff408910fc6b23b2ad62da767db7c28531213f53e2dd91fbd23f01"}}
